LUBRIGATING AND PACKING DEVICE FOR SHAITS.

specification of Letters Patent. Patented Apr, 19, 1921.

Application filed December 16, 1919. Serial No. 345,188.

To all whom it may concern:

Be it known that I, Josnrrr T. AUGER, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Im rovements inLubricating and Packing evices for Shafts, of which the following is aspecification.

My invention relates to lubricating and packing devices for shafts, andan ob ect is to rovide a device of this character which wil efficientlylubricate the shaft by continuously supplying small quantities oflubricant. Another object is to provide a device in which is embodied apacking or stufling box which will make a tight joint with the shaft,and prevent the escape As shown in Fig. 1, the end of the through thesame of water or other fluid.

The full objects and advantages of my invention will appear inconnection with the detailed descri tion thereof, and the novel featuresembodied in my inventive idea will be articularly pointed out in theclaims.

Iii the accom anying drawings which illustrate the app ication of myinvention,

Figure 1 is a sectional elevational view. Fig. 2 is a cross-sectionalview taken on the line 2-2 of Fig. 1. Fi 3 is a side view of alubricating rin ig. 4 is a fragmentary sectional e evational view of amodification.

Referring to the particular construction shown in the drawlngs, 10designates a shaft which extends through a casin or other Walledstructure 12 which is provlded with an annular flange 14 which surroundsthe shaft outside of the casing and constitutes a stuifing box for theshaft. A receptacle 16 for lubricant, such as hard oil, has an inneropen end extending through the stufiing box adjacent the member 12, andthis receptacle may be rovided with the customary screw-threa ed member18 for forcing the lubricant down into the receptacle. Adjacent theinner end of the receptacle 16, and loosely surrounding the shaft is aring 18' having a groove 20 in its circumference and having radial holes22 leading from the groove to the inner margin of the ring. The ringlies at the inner end of the stuffing box, and upon the ring is placedpacking material 24, such as hemp iacking.

ange 14 is externally threaded to receive internal threads on a flange26 carried by an annular nut 28 which has an inner flange 30 adapted tofit between the shaft 10 and the flange 14, and which when the nut isturned down compresses the packing 24. The body of the nut 28 and t econcentric flanges 26 and 30 are preferably formed as an integral unit.The ring 18 in addition to the radial holes 22 may also be provided withholes 32 crossing the holes 22 at right angles thereto, as shown in Fig.4. In this figure an annular flange 34 corresponds to the flan e 14,previously referred to, but is internally threaded to receive theexternally threaded flange 36- of an annular nut 38 surroundin theshaft. The ring 18, as shown in Flg. 4, is placed between rings 40 and42, and it will be understood that the inner end of a lubrieatingreceptacle 16 lies adjacent the circumferential groove in the ring 18 soas to deliver lubricant thereto in the manner shown in Fig. 1.

The operation and advantages of my invention will be readily understoodfrom the foregoing description. The lubricant passes from the receptacle16 into the circumferential groove 20 from which it is carried to theinner margin of the ring through the holes 22. The nut 28 which may beconveniently made from a sin le piece of metal serves to compress thepacking 24 and make a tight joint to prevent water or other liquids fromescaping past the same. In the form of lubricating ring shown in Fig. 4,the additional holes 32 provide for lubricating the sides of the rings40 and 42.

I claim:

1. A lubricating and packing device for shafts comprising a boxsurrounding the shaft and spaced therefrom, a ring at the inner end ofsaid box surrounding said shaft, said ring having a circumferentialgroove and holes leading therefrom to the inner-margin of the ring,means for supplying lubricant to said groove, packing material incontact with the outer side of said ring, and means for holding saidpacking material under compression.

2. A lubricating and packing device for shafts comprising a boxsurrounding the shaft and spaced therefrom, a lubricating receptaclehaving an open end extending into said box, a ring at the inner end ofsaid box surrounding said shaft, said ring having a circumferentialgroove adapted to receive lubricant from said receptacle and havingholes leadin from said roove to the innermargin o the ring, pac ingmaterial in contact with the outer side of said ring, and a nutengageable with the end of said box for holding said packing materialunder compression.

3. A lubricating and packing device for shafts comprising a boxsurrounding the shaft and spaced therefrom, a lubricant receptaclehaving an open end extending into sald box, a ring at the inner end ofsaid box surrounding said shaft, said ring having a circumferentialgroove adapted to receive lubricant from said receptacle and havingholesleading from said groove to the inner margin. of the ring, packingmaterial in contact with the outer side of said ring, and a nut adaptedto be screwed upon the end of said box, said nut having an integralannular flange fitting between the shaft and said box for holding saidpacking material under compression.

In testimony whereof I hereunto afiix my signature.

JOSEPH T. AUGER.
